We are in material world, so we act like a material body. Most of them forget, we are souls.
If we run behind the Material life, you can’t be satisfied. You have to work towards the satisfaction of the life.
How to attain satisfaction? Man must poses a goal in life. He must work dedicatedly towards the goal. He should perform his duties and be responsible for his relations in this world without attachment.
Material mind can’t be satisfied. If your ultimate goal is get a new car. After getting it, you started working to get a home or bike. Keep going.
So make your mind to realize that you are soul. Get away from the material desires. Find what is your goal. Every goal which has a meaning is sparked by the light of god.
Do your duty and enjoy the process of attaining it rather than attaining completely and enjoying.
